WARP-LINKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 396,554, dated January 22, 1889.

Appleman med April 11, 1887.

To all whom. it may concern:

Be it known that we, RICHARD GARsED, JOSHUA GARsED, and WILLIAM MAsoN, all citizens of the United States, and residents 5 of Philadelphia, Pennsylvania, have invented certain Improvements in larp-Linking Machines, of which the following is a specification.

The object of our invention is to form by machinery a double-linked warp similar to that now made by hand, our invention being an improvement Aupon the machine shown in the Patent No. 25,501, granted September 20, 1859, to Richard Garsed and Clayton Denn. This machine formed what is called a single-linked warp, which, however, is objectionable, as it is inconvenient to dye, the warp being loose and the links long and thin, whereas a double-linked warp is compact and thick, the links being close together and the chain of warp only about one-half as long as that of a single-linked warp.

In the accompanying drawings, Figure 1 is a side view of our improved double-linking device, which is secured to or forms part of a machine similar to that illustrated in the above-mentioned patent. Fig. 2 is a section on the line 1 2, Fig. 3. Fig. 3 is a front view of the device with parts of the operating mechanism omitted to avoid confusion, and Figs. 4 to 9 are diagrams illustrating the operation of the linking devices.

Referring to the diagrams, A A are two arms, and B Bv two fingers, which slide in the arms, said arms and fingers being precisely alike and similar to the single arm and linger of the patent above referred to.

A short distance above these arms is suspended a tube or funnel, D, the lower end of which is caused to move in a path similar to a ligure 8, and shown by dotted lines in Fig. 4, the end of the tube first passing around the outside of the end a of the arm A, then returning back of the point of said arm to the central position, then `passing outside the point CL of the arm A, and then returning back of the point a of said arm to the central position, while the lingers B B have a reciprocating motion, one finger being fully serai No. 234,388. (No modem projected when the other linger is fully re- 5o tracted.

Referring to Fig. 5, it will be seen that the tube D is in the central position, the linger B on its outward movement, and the linger B on its inward movement. A loop of warp- 5 5 thread has been placed on the hooked end of the arm A, and the projecting portion b of the linger B is in the act of throwing a previously-formed loop over the same, while a loop of warp -is resting on' the other arm, A 6o and the hooked projection c of the finger B is in the act of taking this loop of warp and drawing it up to the positionshown inFig. 6, the linger B of the arm A having then been projected beyond the point dof the arm A so as to throw the previously-formed loop over the loop just hung on said arm A, as shown. On the return movement of the linger B the loop on the portion b of the linger B will be pushed off, as shown in Fig. 7, and the"7o hooked portion c will engage with the loop hung on the arm A. In the meantime the tube D has passed around the end a of the arm A', as shown in Figs. 6 and 7, and placed a loop of warp on said arm A. On the forward movement of the linger B its portion b carries the old loop previously formed on the arm over this newly-formed loop, the action being the same as the previ ously-described action of the finger B. Re- 8o ferring again to the arm A and its finger, the portion c of said linger, as the latter is retracted, draws a loop on the arm A to the position shown in Fig. 8, and a new loop is placed over the finger, as shown, by the tube D. As 8 5 each linger is retracted, the loop drawn back thereby is caused to ascend the inclined portion of the corresponding arm, and is deposited on the reverse incline at the top of said arm, as set forth in the patent referred to 9o above, so that when the nger is again projected the loop will be in position to be caught by theportion b or b of said linger, and thus supported above the hooked outer end of the arm, over which it is thrown by the linger.

The above described operation produces what is termed a double-linked warp, as shown in the diagram, Fig. 9.

XVe have thought it best to first describe the operation of the main parts of the machine before describing the operating mechanism therefor, which is shown in. Figs. l, 2, and 3.

E E are the side frames of the machine, which are mounted on a beam and situated in respect to the warpiiig-machine and its spools in precisely the same manner as in the aforesaid patent.

F is the main dri ving-shaft, having fast and loose pulleys f f', and on this shaft is the wheel G for feeding the warp to the linking devices. i Y

H is a presser-wheel above the feed-wheel G, the journals of this wheel H being'adapted to vertical slots in the frame, so that the wheel can rise and fall to suit different thicknesses of yarn.

The fingers B B' are pivoted to slides l I', which are guided in V-shaped bearings J, attached to the side frames, E E, and K is a crank-shaft having two cranks, 7c 7.1', diametrically opposite to each other, the pin of the crank 7a being connected by a rod, L, to a pin, Z, on the carriage I, and the pin of the crank 7a' being connected by a rod, L', to a pin, Z',

on the carriage I', so that when one carriage is at the limit of its outward movement the other carriage will be at the limit of its rearward movement.

The arms A A', which are secured to the outer ends of the bearings J, are of the peculiar shape shown, and the fingers B B have projections b Z2', the edges of which are grooved at b2 for the reception of rails a2 on the hooked points a of the arms, the projections traveling on these rails as the finger is approaching the limit of its outward movement, but dropping from the rails before it reaches this limit. Each of the fingers B B' at a certain point in its rearward movement is lifted by a pin, m, sliding in an opening in the arm A and having a friction-roller at its upper end, this pin being actuated by an eccentric, fm', on the shaft K, through the medium of a lever, M, pivoted to a bearing on the under side of the guide J. The eccentrics m' for each finger are precisely alike, but are set opposite to each other to accord with the set of the cranks.

y The pins m, levers M, and eccentrics m' are lomitted from the front view, Fig. 3, as it is thought that their illustration in-this View would tend to confuse and render obscure the parts of the operating mechanism which are there illustrated.

Asbefore remarked, thelower portion of the tube D has a motion in the form of a figure 8. The vibrating motion'to right and left, as shown by the arrows, Fig. 3, is effected in the following manner: The upper portion of the tube D has, two journals, d d,which are adapted to bearings a n on a swiveled bracket, N, which has its bearing in a block, p, secured to a brace-bar, P,'extending froml one frame,

E, to the other, as shown in Fig. 3. To the rear end of the swiveled bracket N we secure a slotted arm, n', which engages with a pin, q, on a reciprocating bar, Q, the latter havinga pin, q', which engages with a slot in a cam, R, secured to a shaft, S, having its bearings 4in the frame of the machine. This cam moves the tube D from its central position to the position shown by the dotted lines 2, Fig. 3, and then returns the tube to said central position and permits it to rest for a short time in this position, after which the tube is moved to the position shownby the dotted line 3 and then to the central position, fromwhich, after a proper dwell, it is again moved to the position shown by the dotted line 2, and so on. In the meantime a slotted cam, T, also on the shaft S, vibrates the tube in the direction of the arrows, Fig. 2-that is to say, in a direction at right angles to the vibrations just describedthe tube having an arm, d', which passes through an orifice in an arm, t2, of the vertical reciprocating bar t, having a pin, t', engaging with the slot of the cam T, as shown in Fig'. 2.

On the driving-shaft F is a gear-wheel, 4, meshing with a wheel, 5, mounted on a stud, 9, adjustable in a slot in the frame. This wheel 5 gears with a wheel, 6, on the camshaft S, and this wheel in turn is geared with a wheel, 8, on a crank-shaft, K, through an intermediate wheel, 7, on a stud mounted on a bracket secured to the frame, as shown fully in Fig. l. By having the wheel 5 adjustable the wheel l can be replaced by a wheel of any desired size, and thus the speed of the linking devices can be varied in respect to the rate of delivery of the warp, the length of link being thus graduated to suit the bulk of the warp which is being linked.
